Need Help

[downhill32]

hay all,

my problem is i recently installed a boost controller and wound my turbo(stock) to 12.5psi.now when full boost hits somewhere between 4500-5000rpm the exhaust starts to make a poping sound and the car starts to miss fire(wont pull anymore).my car is a r32 gtst with a full exhaust,fmic,chipped ecu,pod filter.my thoughts are that it could be one of 4 things the coil packs which i checked today seem ok,the spark plugs, or that the injectors or fuel pump is maxing out,

any help would be great.

thanks

you've solved your own problem - I bet your plug gaps are not 0.8mm

thanks will try that tomorrow,can you do it yourself or do you need a mechanic to do it?

An R32 GTSt with a good exhaust, intercooler and air filter will basically make 12psi without a boost controller. Was that eh case? If not then you could have another problem

actuator for r32 turbo is at 10psi.. so wont really go to 12 unless its really cold...

u will need to regap ur spark plugs.. takes an hour out of ur time... ive got mine down to .65mm

works a charm
